Frames made with TR90 are extremely comfortable. Since they are flexible, they can bend under pressure and contour your customer's face comfortably. Because of the TR90 frame's flexibility, it also makes them resilient to damage. WHAT IS A BLUE BLOCK LENS? Blue-light-blocking glasses have filters in their lenses that block or absorb blue light and in some cases UV light, from getting through. That means if you use these glasses when looking at a screen, especially after dark, they can help reduce exposure to blue light waves that can keep you awake.
